Creating a Warning Using the Failure API

The Failure API enables both failure definition and handling capabilities – The ability to define and post failures from within API code when a user-visible problem has occurred – The ability to respond to failures posted by Revit and by API code through code in your application This also enables the creation of a modeless warning message to the user...

Getting All Parameter Values

How to export all the Revit data to an external database? It is very simple to extract all the parameter data. Let's implement a solution to do so – Existing sample implementations – Black box input – Choices for the output and its structure – Retrieve parameter values from an element – FilterCategoryRule versus category filters – Category description extension method – Retrieve parameter data for all elements of given categories – External command Execute mainline – Sample run results – Download...

Retrieving Newly Created Element Ids

An add-in will often need to retrieve the elements that it just created for further processing. Frequently, the Revit API method used to create them will return their element ids. Sometimes, that is not the case. Now this topic arose again in a couple of cases and brought some other aspects to mind – Using the element lister – Consecutive element ids – Retrieving recently added elements – AEC job openings in Munich and elsewhere...
